Hi guys, I'm stuck with this and found no solution yet:
Using promise ultra100 card for hard drives and onboard ata66 controller for lite-on 52246s cdrw and plextor px-712a. Both cdrw/dvdrw support udma2, yet neither controller allows me to run them in Win XP at udma mode 2. For the cdrw no big deal, but I can use the extra speed for the plextor drive.
Here are the problems; connecting the optical and disk drives to the promise card, card's boot sequence shows udma mode 5 for the drives and udma mode 2 for the optical disks. But screen freezes at windows boot screen normal/safe mode. Connecting the optical drives to the onboard controller, the mode on both drives stays at Multi-word dma 2.
I've installed hyperion ide accelerator driver, via ide miniport driver, and ultra bus master to change the mode but no success. I have not installed the complete via hyperion or 4-in-1 drivers, because I dont want to test my luck with the setup and play around with system restore
Is having both hard and optical drives on the promise controller card, good or bad idea?
Anyone have suggestions on what I should try?
Computer setup:
Win xp pro, msi pvx6a motherboard, 1gb ram 1ghz p3.
Two harddrives connected to ide1 of promise ultra100 tx2 card using ata100 cable, and optical drives connected to onboard ide2.
